Australian Maritime Boundaries Information System (AMBIS) 2001 (Version 1.1)  

Authors / CoAuthors

Abstract

Geoscience Australia is responsible for the definition of Australia's maritime boundaries. To assist in this task National Mapping has developed the Australian Maritime Boundaries Information System (AMBIS). AMBIS 2001 is a data product, derived from AMBIS, providing access to the data for Australia's Territorial Sea Baseline (TSB) and maritime zones. AMBIS 2001 data comprises the TSB and the outer limits of each zone, together with quality attributes. Base points that generate the zone boundaries are supplied in separate files and an extensive user guide provides useful background information. All data coordinates are supplied in the Geocentric Datum of Australia (GDA 94) which is effectively identical to the WGS84 datum. National Mapping is committed to the maintenance of the AMBIS data to ensure it reflects the changing nature of Australia's coastline and hence the various maritime zone limits. To this effect, a newly revised AMBIS 2001 product (version 1.1) has been released in October 2001. This new version incorporates additional treaty information, additional data in the vicinity of Swains Reef in Queensland, an improved representation of the TSB, several other minor corrections, a wider range of formats and simplified attribute tables.

Lineage

The Territorial Sea Baseline (TSB) data was originally derived from the National Mapping Division's 1:100 000 scale coastline data supplemented with coastal aerial photography in some areas. Since 1994 the data has been extensively validated and revised using the best available data from the National Mapping Division, the Australian Hydrographic Office and all State and Territory mapping agencies. Satellite imagery and recent aerial photography were also used. The boundaries have been rigorously computed from the TSB using MARZONE software developed specifically for this purpose by the Department of Geomatics, University of Melbourne under contract to the National Mapping Division.
